What “jetstream” means
Wiktionary · Wikipediajetstream
- nounAny of the high-speed, high-altitude air currents that circle the Earth in a westerly direction
Jet streams are fast flowing, narrow air currents in the atmosphere. It is the physical mechanism of a teleconnection. The main terrestrial jet streams are located near the altitude of the tropopause and are westerly winds, flowing west to east around the globe. The Northern Hemisphere and the Southern Hemisphere each have a polar jet around their respective polar vortex at around 30,000 ft above sea level and typically travelling at around 110 mph (180 km/h) although often considerably faster.
